COMBINED ROLLER SHADE BRACKET AND STOP Patented Jan. 7, 1941 UNITED STATES PATENT OFFICE COMBINED ROLLER SHADE BRACKET AND STOP 1 Claim.

This invention relates to shade roller fixtures as applied to window embrasures to support opaque fabric sheets attached to a roller in a manner permitting raising and lowering the shade at will.

Ordinarily the shade is provided with a seamed lower edge receptive of a stiffener strip, while the roller contains a torsional spring having sufficient force to cause winding of the shade material when the roller detents are released from the cam device at the roller end.

When such release occurs the shade, unless restrained, is rapidly coiled upon the roller and frequently its free end carried therearound until the spring becomes exhausted, entailing the difficult and disagreeable Work of removing the roller from its supports and readjustment of the spring.

It is therefore an object of the invention to provide an effective device, operable automatically to prevent the possibility of such occurrence.

A further feature is in the provision of a stop at each side fixture, adapted to contact the stiffener strip, when raised to its limit, retaining it in a readily accessible position and without n any way injuring the material.

Another purpose is to produce an approved type of shade roller fixture having integrally combined with it a positive stop, preventing an excessive movement of the shade, and which is concealed from ordinary observation.

These objects are accomplished by the novel construction and arrangement of parts hereinafter described and illustrated in the accompanying drawing, constituting a material component of this disclosure, and in which:

Figure 1 is a fragmentary perspective view of the several elements included in the invention, as disassociated.

Figure 2 is a side elevational view of one of the pair of fixtures.

Figure 3 is a similar view of the mating fixture, indicating its relation to a shade shown in broken lines.

Figure 4 is a top plan view of a complete embodiment of the device as assembled relative to a window.

Figure 5 is a transverse sectional view taken on line 55 of Figure 4.

Referring in greater detail to the drawing, the

50 numerals l5-l6 designate in general the upright sides of a conventional window frame having secured on their inner sides brackets |'|--l8 of substantially the usual type of construction.

The bracket I! has an inwardly extending boss I!) provided with a central circular opening 2!,

while the opposite bracket l8 has a similar but slightly larger boss 20 shaped to produce an elongated vertical slot 22, enterable through a passage 24 in its upper front portion.

A roller 25 has attached to it the inner end of 5 a shade 26, its free end having an open transverse hem 21 to contain a stiffening strip 28.

One end of the roller has a pintle 29 suited to rotate in the opening IS, the opposite end portion of the roller bored to receive a torsion 10 spring, not shown, operating to exert winding pressure on a stem 30 suited to enter and be retained in the slot 22.

Fixed in the stem 30 is a cam 3|, recessed upon opposite sides to engage gravity operable dogs 32 18 pivoted on the end of the roller, all the foregoing being old and well known, but given that a clear understanding of the invention may be had.

Extending rearwardly from the brackets l'l-IB are flat arms 31-38 of uniform definite length 20 leading to inreaching, concavo-convex stops 39-40 of such length as to extend into zone of the "shade 26.

It'will be noted that the convex sides of the stop are presented towards the shade, and it 25 will be readily understood that the distance the arms 3'l38 extend from the axes 2930 should be equivalent to the radius of the shade when fully rolled, so that when this occurs the shade shrouded strip 28 is intercepted by the stops, pre- 30 venting further movement of the shade.

It will further be seen that the stops and brackets are of one-piece construction capable of inexpensive manufacture, and further, it may be noted the stops are not perceptible from the 35 front, as they are disposed directly rearward of the roller.

Having thus described the invention and set forth the manner of its construction and application, what is claimed as new and sought to 40 secure by Letters Patent, is:

A shade roller fixture for use with springwound shades which have a thickened bottom edge, said fixture comprising a. fixed bracket, an inwardly extending boss on said bracket, said boss having an opening therethrough, a flat arm extending rearwardly of the bracket and a stop unit integral with and disposed at right angles to said flat arm and extending rigidly into the path of said thickened bottom edge to prevent l0 excessive winding of the shade, said stop unit being concavo-convex in cross-section to impart rigidity to the fixture.
